Bosch 0986021360 Starter

Overview of the Bosch 0986021360 Starter

The Bosch 0986021360 Starter is a high‑performance electric starter motor designed for use in a wide range of Mercedes‑Benz vehicles, including the C‑Class, E‑Class, CLK, Sprinter vans, and various other models. Manufactured by Bosch, this starter delivers reliable ignition performance with a robust 1.7 kW output at 12 V, ensuring quick engine start-up even under demanding conditions.

Key Performance Characteristics

• Power Output: 1.7 kW (2.3 hp) – sufficient to crank most medium‑sized engines.
• Voltage: 12 V DC – standard automotive battery voltage.
Rotation Direction: Clockwise (right‑handed) – compatible with the majority of Mercedes‑Benz engine designs.
• Thread Size: 2 mm × 1.5 mm – matches OEM specifications for secure mounting.
• Teeth Count: 12 – provides smooth engagement with the flywheel or flexplate.

Design and Build Quality

The starter is constructed from high‑strength steel housing, which protects internal components against vibration, heat, and corrosion. The motor windings are insulated with premium materials to withstand high temperatures during operation. A built‑in self‑synchronizing clutch ensures that the starter engages only when the engine crankshaft reaches the correct position, reducing wear on both the starter and the flywheel.

Vehicle Compatibility

The Bosch 0986021360 Starter is engineered to fit a broad spectrum of Mercedes‑Benz models. Below are some representative vehicle families and model years for which this starter provides an exact match:

• C‑Class (W204) – 2007–2014, 2.5 L, 3.0 L, 3.5 L engines.
• E‑Class (W211) – 2006–2009, 2.1 CDi, 2.5 CDi, 3.0 CDi variants.
• CLK (C209) – 2005–2009, 2.2 L engines.
• Sprinter Vans – 2006–2014, 2.1 CDi, 3.0 CDi, 3.5 T models.
• CLC‑Class (CL203) – 2008–2010, 2.1 L engines.

For each of these vehicles, the starter’s dimensions—238 mm in length and a standard 12‑tooth gear—match OEM specifications, ensuring a seamless fit without the need for modifications.

Installation Notes

1. Disconnect the battery: Always remove the negative terminal before working on the starter to avoid electrical shock.
2. Remove the old starter: Detach the mounting bolts and carefully lift out the existing unit. Note that some models may require removal of ancillary components such as the ignition switch or wiring harnesses.
3. Position the new starter: Align the 12‑tooth gear with the flywheel teeth, ensuring correct orientation for clockwise rotation.
4. Tighten mounting bolts: Secure the unit using the supplied torque specifications (typically 20–25 Nm).
5. Reconnect wiring: Attach the high‑current connector and any auxiliary sensors. Verify polarity before final connection.
6. Test operation: Reconnect the battery, activate the ignition, and observe smooth cranking without excessive noise or vibration.

Technical Specifications Summary

Why Choose the Bosch 0986021360 Starter?

The Bosch 0986021360 Starter combines proven engineering with modern materials to deliver:

• Reliability: Designed for long service life under high‑current conditions.
• Ease of Installation: Standard mounting and wiring interfaces reduce labor time.
